How we quote for commercial sealant
We don’t publish a price list. What we look at:
- The product the joint needs
- The number of rooms or windows
- The number and length of the joints
- Any working-time requirements on site
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Whether it’s a home or a business
- Where the property is
- How many joints, rooms or windows are involved
- How we’d reach the joints
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. Whenever you’re ready, phone 0345 464 0079 or drop us an email.
How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Pass on the cure time to whoever cleans the rooms
- Use mild cleaners on sealant, not bleach or abrasives
- Check the joints during routine room inspections
- Book larger programmes for quieter times of year
Keep the extraction running and maintained. Where a room has no window, the fan is what dries it out, and that’s what keeps mould away.
Planned resealing is easier to manage than emergency repairs. We can fit the work around bookings, shifts and opening hours, rather than closed at short notice.
DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Work for landlords, hotels and businesses
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Letting agents often deal with us directly. Tell us the address, the job and how access works.

What else we do in North Cray
Workplaces and buildings in North Cray
London has hard water, so limescale builds up on sealant, grout and fittings. Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed.
If you look after a church, hall or community building such as Parish Church of St James, halls and community kitchens see heavy use, and their sealant shows it. North Cray is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Letting a property close to Albany Park station? Then several rental properties can be resealed on one programme.

North Cray questions
Is parking an issue for commercial sealant in North Cray?
Parking in North Cray, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you work for landlords with property near Albany Park station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Can the hotel stay open while you work?
Yes, in most cases. We agree a batch of rooms for each visit.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
How soon can a room be used after resealing?
Around 24 hours is typical for sanitary silicone. Housekeeping get the cure time for each room.
How long does commercial sealant take?
As a guide, most jobs take a few hours per room, so whole buildings are phased. Larger jobs naturally take longer, and we’ll say how long yours will take.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
How the visit works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself usually takes as long as the scope needs, from one welfare room to a full building, depending on how much there is to do. For a job in North Cray, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- The first visit is a look round the site to agree the scope.
- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
- Areas are protected and the failed sealant removed.
- Joints are dried, then resealed and tooled neatly.
- Housekeeping or site staff are told when each area can be used.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- On commercial sites, let us know about site rules
- Let us know if you’ve seen damp or leaks

Advice
Leave it or put it right?
Sealant work is quick by the room: the job takes anything from a few hours to several days, depending on the number of rooms. Each area is then left to cure for the time we give you, so the programme is planned around cure times. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
